(CNN) -- President Barack Obama on Friday defended the the "vital role" that intelligence-gathering plays in the nation's security, as he nonetheless announced changes aimed at increasing transparency and protecting privacy and civil liberties.

Presidential guidance released as Obama spoke at the Justice Department said the government will not collect intelligence "for the purpose of suppressing or burdening criticism or dissent, or for disadvantaging persons based on their ethnicity, race, gender, sexual orientation, or religion."

(CNN) -- President Barack Obama on Friday will announce the end of the controversial NSA telephone metadata collection program "as it currently exists," a senior administration official told CNN.

From CNN Justice Reporter Evan Perez: In the Justice Department ceremonial Great Hall, heavy security and limited admission only to dignitaries such as government lawyers and members of Congress make it unlikely we'll have protesters such as Code Pink who have disrupted past presidential speeches.

There is a curtain blocking off the partially nude statues in the hall, which garnered controversy during the tenure of Attorney General John Ashcroft (he had them draped with a cloth for modesty).

What's the impact of NSA data collection?

Retired Maj. Gen. James 'Spider' Marks says he doubts anything is going to "substantively change" in terms of using data collection to go after terrorism.

The White House has just about acknowledged that it has spied on world leaders, including allied leaders, CNN Senior White House Correspondent Jim Acosta reports. The president is also expected to announce a "privacy advocate" to the federal surveillance court.

Per CNN's Wolf Blitzer, one thing to look for in the President's speech: Will Obama mention Edward Snowden by name?

FBI Director James Comey and Attorney General Eric Holder just walked in, meaning the President should follow shortly.

"Throughout American history, intelligence has helped us" secure freedom, Obama said, citing Paul Revere's patrolling of the streets during the American Revolution to see if the British were planning any raids as a first example.

From CNN Justice Reporter Even Perez: Internet coverage is spotty in the Great Hall. I am told by the DOJ that this is just a common thing as the building is very old. Irony isn't it? The one place where the NSA probably can't collect our data because we are disconnected.

After 9/11 "we had to adapt" to a new world. "We were shaken by the signs we had missed leading up to the attacks...so we demanded our intelligence community improve its capabilities."

by CNN's Ashley Killough1/17/2014 4:21:43 PM

After 9/111, the job given to the intelligence community was enormous, Obama said, saying the priority became prevention of terrorism attacks, rather than chasing terrorists after they've already carried out violence.

New presidential guidance on U.S. surveillance unveiled by Obama says the government will not collect intelligence "for the purpose of suppressing or burdening criticism or dissent, or for disadvantaging persons based on their ethnicity, race, gender, sexual orientation, or religion."

by CNN's Ashley Killough1/17/2014 4:23:04 PM

The official guidance released Obama delivered a speech also "signals that intelligence shall be collected exclusively where there is a foreign intelligence or counterintelligence purpose to support national and departmental missions and not for any other purposes."

Funfact: 1 of the first bills Obama co-sponsored as sebator would have made bulk collection of phone metadata under Section 215 impossible.

"Intelligence agencies cannot function without secrecy...yet there is inevitable bias...to collect more information about the world, not less. So in the absence of institutional requirements...and oversight that is public...the danger of government overreach becomes more acute."

Obama said he maintained a "health skepticism" of the NSA programs after he became president and made some changes....But he defended the purpose of the agency: "What I did not do is stop these programs wholesale."

"The men and women at the NSA know that if another 9/11 or massive cyber attack occurs, they will be asked by Congress and the media why they failed to connect the dots," he says. What sustains NSA employees is that their work plays a "central role in the security of our nation."

"Given the fact of an open investigation, I’m not going to dwell on Mr. Snowden’s actions or motivations."

From CNN Senior White House Correspondent Jim Acosta: DNI James Clapper on the intelligence reforms being announced by the President:

"The President took a measured and thoughtful approach to the intelligence reforms he's directing today. These adjustments and those under consideration are focused on striking the right balance between making sure we have the tools necessary to conduct intelligence, that we are being as transparent as possible and that we're not violating the civil liberties and privacy of innocent Americans. His decisions were guided by recommendations from the Review Group on Intelligence and Communications Technologies, the Privacy and Civil Liberties Oversight Board, and close consultation with Congress and IC leaders. "

"I was gratified that he expressed his continued confidence in the men and women of the Intelligence Community. He recognized the IC workforce for performing extraordinarily difficult jobs where success is rarely celebrated, but is vital to our national security. It's something our workforce needed to hear after what has been a challenging past several months.”

"I will say that our nation’s defense depends in part on the fidelity of those entrusted with our nation’s secrets. If any individual who objects to government policy can take it in their own hands to publicly disclose classified information, then we will not be able to keep our people safe, or conduct foreign policy."

POTUS defending work of intel community - "including the #NSA " - says they're not abusing their authority or reading your emails.

"Moreover, the sensational way in which these disclosures have come out has often shed more heat than light, while revealing methods to our adversaries that could impact our operations in ways that we may not fully understand for years to come."

NSA employees who have grumbled at weak defense of their work by admin, will find a lot to like in president defending them in this spch

by CNN's Ashley Killough1/17/2014 4:30:29 PM

"Regardless of how we got here, though, the task before us now is greater than simply repairing the damage done to our operations; or preventing more disclosures from taking place in the future. Instead, we have to make some important decisions about how to protect ourselves and sustain our leadership in the world, while upholding the civil liberties and privacy protections that our ideals – and our Constitution – require."

Obama's telling of recent history of these programs completely skips over the fact that FISA ct found massive compliance problems w/215&702.

by CNN's Ashley Killough1/17/2014 4:30:54 PM

"We need to do so not only because it is right, but because the challenges posed by threats like terrorism, proliferation, and cyber-attacks are not going away any time soon. They are going to continue to be a major problem. And for our intelligence community to be effective over the long haul, we must continue to the trust of the American people, and people around the world."

"This effort will not be completed overnight, and given the pace of technological change, we shouldn’t expect this to be the last time America has this debate. But I want the American people to know that the work has begun."

"Over the last six months, I created an outside Review Group on Intelligence and Communications Technologies to make recommendations for reform. I’ve consulted with the Privacy and Civil Liberties Oversight Board. I’ve listened to foreign partners, privacy advocates, and industry leaders. My Administration has spent countless hours considering how to approach intelligence in this era of diffuse threats and technological revolution. So before outlining specific changes that I have ordered, let me make a few broad observations that have emerged from this process."

by CNN's Ashley Killough1/17/2014 4:32:33 PM

"First, everyone who has looked at these problems, including skeptics of existing programs, recognizes that we have real enemies and threats, and that intelligence serves a vital role in confronting them. We cannot prevent terrorist attacks or cyber-threats without some capability to penetrate digital communications – whether it’s to unravel a terrorist plot; to intercept malware that targets a stock exchange; to make sure air traffic control systems are not compromised; or to ensure that hackers do not empty your bank accounts."

"Moreover, we cannot unilaterally disarm our intelligence agencies. There is a reason why blackberries and I-Phones are not allowed in the White House Situation Room. We know that the intelligence services of other countries – including some who feign surprise over the Snowden disclosures – are constantly probing our government and private sector networks, and accelerating programs to listen to our conversations, intercept our emails, or compromise our systems."
